Abstract
This hand position adjuster allows the operator to adjust the position of the lower connect while on board the vehicle. Either tool end of the lower connect is arranged with a cable holder, wherein, the one on connect A being the free type and the one on connect B being the limit type. The original two limit hauling chains are reduced to one, each end of which is arranged with a bridle to adjust the tightness degree of the chain. The limit chain is connected to the lower connect in a cross circulation manner.
Description
Technical field
The utility model relates to the position regulator of lower link in the farm tractor suspension, and particularly it can sit onboard gently rotation crank, just can change the position of lower link.
Background technology
At present, the adjusting device that tractor hangs lower link is to draw two iron chains that have strainer in the middle of towing plate, be hung on the tie point of two suspension lower links and brace, when running into batter during agro-farming, the downward hill wash of farm implements moves, need the adjustment draw rod positions to drive the farm implements upward slope and move, with the slippage of compensation farm implements descending.The length of adjusting two strainers of so just must getting off changes the position that hangs lower link.
Summary of the invention
In order to overcome present situation, the utility model provides a kind of hand-rail type to hang the lower link position regulator, and it shakes gently just can change the position that hangs lower link, and then difficulty from the driver to the slippage of descending that bring to of change farm implements.
The scheme that this utility model solves this technical problem is: hang lower link extension farm implements end with two a chain cable fairlead respectively is housed, what wherein adorn on the A pull bar among Fig. 2 is the free style chain cable fairlead, and what adorn on the B pull bar is spacing chain cable fairlead.Spacing slide fastener changes one into by two, and the spacing slide fastener of this root is connected with suspension lower link two ends with the intersection endless form.Method of attachment: one terminates at the A pull bar worries on the spacing slide fastener hook of this end of corbel back slab, and the other end passes the spacing chain cable fairlead on the B pull bar, passes the free chain cable fairlead on the A pull bar again, receives the B pull bar and worries on the spacing slide fastener hook of corbel back slab one end.
Spacing chain cable fairlead by: form spacing chain cable fairlead with the big retarding tooth of chain cable fairlead one and the little deceleration in the big retarding tooth and the little axle of off-centre, a spacing chain cable fairlead support.What be connected with the little axle of off-centre on the support is universal joint, and universal joint is connected with crank, and a crank support is arranged on the crank.The deceleration principle is to stretch out the forearm of a pin with lock on its medium and small deceleration tooth.Lock pin on the forearm is placed in the opening on the spacing chain cable fairlead supporting plate, little deceleration tooth can not be rotated, can only when the little axle of off-centre rotates, drive little deceleration tooth and big retarding tooth and do the meshing motion of gear and gear, so just form big retarding tooth and little deceleration tooth the number of teeth difference this be eccentric little axle and the rotating ratio of spacing chain cable fairlead canine tooth, to reach the purpose of deceleration.Because spacing chain cable fairlead canine tooth is fixed on the lower link chain cable fairlead support, thus when spacing chain cable fairlead canine tooth rotates, the spacing slide fastener length on chain cable fairlead both sides is changed, the change of spacing slide fastener length, feasible change of hanging the lower link position.Spacing principle: because when eccentric little axle does not change, little deceleration tooth can not rotate under the effect of lock pin, so the meshing stop that has just become to subtract greatly tooth of little deceleration tooth one big retarding tooth remains unchanged the spacing slide fastener length on spacing chain cable fairlead both sides, reaches position-limiting action.
The beneficial effects of the utility model are: sit onboard the position of just speed governing easily suspension lower link, and simple in structure, should operate.

Embodiment
Hanging free chain cable fairlead support 11 of extension farm implements end welding on the lower link A, hanging spacing chain cable fairlead support 1 of extension farm implements end welding on the lower link B, worry the corbel back slab end at suspension lower link A and suspension lower link B and respectively weld a spacing slide fastener hook 14, will hang the crank support 8 of burn-oning on the lower link C again.Earlier a strainer 13 is respectively adorned at spacing slide fastener 12 two ends, the spacing slide fastener one that strainer will be housed again terminates on the spacing slide fastener hook 14 that hangs on the lower link A.After the other end extracts from spacing chain cable fairlead support 1, with spacing chain cable fairlead canine tooth 2, the little tooth 3 chain cable fairlead support 1 of packing into, again the little axle 4 of off-centre is loaded onto, again spacing slide fastener is extracted from free chain cable fairlead support 11, load onto free sprocket wheel 10 then, put on free chain cable fairlead pin 9, at last the strainer on the spacing slide fastener 13 is connected with the spacing slide fastener hook 14 that hangs lower link B.Again crank 7 is worn with universal joint 5 from crank support 8 and be connected loading onto universal joint 5 above the little axle of off-centre 4.
